由于流化床具有固体粒子混合好和传热速率高的特点,对于流化床与浸入表面间传热的研究一直受到广泛的重视。但由于流化床传热机制的复杂性,流化床的传热优化设计仍然是困难的,目前基本上是在经验基础上进行.了解流化床与浸入表面间的传热机制对于流化床的设计和经验关联式的理解都是非常重要的。本文回顾和综述了已发表的主要传热机制和传热模型,以及流化床传热过程参数的确定和选择方法.
Due to the characteristics of fluidized bed being mixed well with solid particles and high heat transfer rate, the research on heat transfer between fluidized bed and immersion surface has been paid more and more attention. However, due to the complexity of fluidized bed heat transfer mechanism, heat transfer optimization of fluidized bed is still difficult to design, and is basically based on experience. Understanding the heat transfer mechanism between fluidized bed and immersion surface is very important for fluidization The design and experience of the bed associated with the understanding is very important. This paper reviews and summarizes the published major heat transfer mechanisms and heat transfer models, as well as the determination and selection of parameters for fluidized bed heat transfer.
